Leaving the watch where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from the watch for long periods can cause it to become discolored.

Friction caused by certain conditions (frequent external force, sustained rubbing, impact, etc.) can cause discoloration of painted components.

If there are printed figures on the band, strong rubbing of the printed area can cause discoloration.

Failure to clean dirt from the watch for long periods can cause fluorescent color to fade. Wash dirt off with water as soon as possible and then dry the watch.

Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high temperatures for long periods.

Contact an authorized CASIO Service Center to have resin components replaced. Note that you will be charged for replacement costs.
